It is very similar to the steam thermostat however it is thicker which means the temperature required to triggers it is higher.

The boil dry thermostat is a safety mechanism that ensures the kettle switches off if there is no water. In these circuit diagrams when the steam thermostat is ‘on’ the indicator light is also on, the circle just under the switch represents the light.

The steam thermostat is reset by pressing the on/off button, which will pushes down the disc, and starts the whole process again. As the disc reaches the set temperature it expands and flips causing the circuit to be broken, this stops the flow of electricity to the heating element. Once the water starts to boil the steam is directed through a ‘steam vent’ to the bimetallic disc. I have found that in a domestic kettle when you press the ‘on’ button the steam thermostat is pushed down, which completes the circuit allowing the electricity to flow through the rest of the circuit. The temperature at which a bimetallic disc will trigger depends on the size and thickness of the disc. In a domestic kettle the disc is roughly 1 cm by 1 cm and triggers at around 98✬. The thermostat is a bimetallic disc that changes shape depending on the temperature. The steam thermostat is the switch that turns the kettle on and off. Heating elements are available in various shapes and sizes and can be customised built if required. As the current passes through the resistor it is converted into heat, this is what boils the water. In a kettle the heating element is the main resistor, which is located in the water reservoir. Next, is the resistor (left hand side) it is represented by a zigzag. The arrow symbol represents the ground connection usually this is a return path for the electric current or a physical connection to the Earth. In first diagram on the bottom right is the power source depending on the design of the kettle this will either be a power plug or some kind of cordless interface system like the Stric P69. Contact us today.In a domestic kettle the basic electrical components are: George Brazil Plumbing and Electrical can help you fix your electric water heater if you live in the Phoenix area. If a plumber has checked out your water heater and everything seems to be working fine, you should have an electrician check the electrical connections.

A wire is loose in the electrical panel, which is causing a short circuit.

The breaker itself is worn out and tripping needlessly.

The problem may not actually be with the water heater. This draws more electricity than the circuit can handle, causing the circuit breaker to trip. However, when a thermostat goes bad, it can create a problem where both heating elements run at the same time. On an electric water heater, only one heating element is on at a time. Bad thermostatĮach heating element is controlled by a thermostat both thermostats “talk” to each other to ensure that only one heating element is on at a time. This short circuit can flip the high limit switch on your water heater and/or cause the water heater’s breaker to trip. Usually, when the heating elements fail, they simply burn out and the only way you’ll notice is that the water isn’t as hot as it once was.īut sometimes, the heating element casing can split and expose the electrical components directly to the water or tank. Most electric water heaters have 2 heating elements: one on top and one on the bottom.ĭiagram of an electric water heater with 2 heating elements. The heating element is the part of your water heater that heats the water. Okay, with that out of the way, let’s look at the possible problems that are causing your electric water heater to trip your breaker. Now the breaker will let additional electricity flow to the circuit, which can overheat wires and cause a fire. If you increase the breaker size without replacing the wiring and the rest of the circuit, you’ve basically just removed the safety device of the breaker.

Do not replace the breaker with a higher-rated breaker.

This can overheat the wires in the circuit (which can lead to a fire), wear out the circuit breaker (which can cause it to not trip later) and damage your water heater further.

Do not keep flipping the breaker back on.

But then a little later your water heater’s circuit breaker tripped again.īut before we get into those problems, there are a few things you need to know: So you went to your electrical panel and reset the breaker. The scenario: You noticed your electric water heater tripped the circuit breaker.
